Fluorine has the atomic number of nine. It has nine protons, nine electrons, and ten neutrons.
It's average atomic mass number is 18.9984032. That means that it's mass number is 19.
Fluorine has a melting point of 53.5 Kelvin and a boiling point of 85 Kelvin.
Fluorine is classified as a nonmetal and is a gas at room temperature.
It's color is a pale yellow at room temperature.
Fluorine is the most reactive of all the elements. This makes it very hard to transport and to store.
Fluorine is a member of the Halogens in group 7A and in period 2.
Fluorine has 16 isotopes, 13 of which are radioactive.
History:
Fluorine was supposedly discovered around the year of 1670 by a group of chemists, using fluorspar (a mineral consisting of calcium floride in crystalline form), that were trying etch glass.
Ferdinand Frederic Henri Moissan was the first person to isolate and produce Fluorine in 1886. He is the official discoverer of the element.
Where is it found?
Fluorine is far too reactive to be found as a natural element. So, it is found in various compounds within minerals such as cryolite and fluorspar.
It was first found when a group of men found fluorspar in a cave in Russia.
It is very rare to find pure fluorine. So, most fluorine elements are found in fluorspar, which is much more common.
What are it's modern day uses?
Fluorine is used industrially to purify uranium for nuclear power stations.
Fluorine is also used in toothpaste to prevent tooth decay (Sodium Fluoride). Toothpaste costs about $4 for 6 ounces.
The plastic on the nonstick surface of many pans contains fluorine.
Fluorine can also be found in lightbulbs and computer chips. Light bulbs cost about $5 for a box of four lightbulbs.
Interesting Fact about Henri Moisson
He is considered the man who discovered fluorine and won the Nobel Prize in 1906 for his actions.
